MOLDING-JACKET.

Specification of Letters Eatent. Pajmnted D 28 1920 Application filed April 25, 1919. Serial No. 292,668.

sand mold in condition after it has been removed from the flask, and has for an object to provide a jacket designed to conform to inequalities in the exterior sides of the mold and to particularly take care of variations in the lengths of the sides at the top and bottom portions of the mold.

Briefly stated, the invention comprises a jacket the sides of which are connected together near the top and bottom portions of the jacket to afi'ord unequal expansions of the top and bottom of the jacket to accommodate the variations in the mold.

With these and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified-and claimed.

In the accompanying drawing,

Figure 1 is a perspective view of a molding jacket constructed according to the present invention.

Fig. 2 is a fragmentary, enlarged section of one corner of the jacket, showing the reinforcing means for the side plate and the connection at the top of the acket.

Referring to the drawin s by numerals, 10 and 11 designate the sides of the jacket which are of suitable length and height and which may be formed of castings. End plates or walls 12 and 13 are detachably and adjustably connected between the opposite ends of the sides 10 and 11 and may also comprise castings. Each end wall is preferably formed with diagonally extending ribs 14: cast integral with the exterior surface of the end and merging together at the central portion of the end for the purpose of reinforcing the end against internal pressure incident to expansion of the mold.

Each side, such as shown at 11 in Fig. 1, 1s provided intermediate its ends with outstanding webs or flanges 15 of substantially triangular shape with the apex remote from the adjacent face of the side 11, the web 15 being formed exteriorly upon the side 11 and constituting a support for a brace rod 16 which is arranged longitudinally of-the side. Ears 17 are secured to the outer face of the side 11 near the ends thereofand are adapted to receive the opposite ends of the brace rod 16 freely therethrough. Clamping nuts 18 are threaded upon the free ends of the rod 16 beyond the ears 17 and are adapted to be turned up against the latter for drawing the rod taut over the intermediate web 15 and strengthening the side 11 againstinternal pressure. The web 15 is preferably provided with a notch 19 at its apex to receive the rod 16 therein for holding the latter from displacement.

The adjacent ends of the sides and end walls of the jacket are provided with outturned ears or lugs 20 which project at substantially forty-five degrees from the adjacent end or side and which are adapted to lie in parallelism with each other for the reception of connecting bolts 21 therethrough. The bolts 21 are fitted with the usual sprin s 22 and the clamping nuts 23 for variably holding the lugs 20 in spaced relation. It will be noted that the lugs 20 are coextensive with the adjacent longitudinal edge portion of the side or end from which the lugs project, and that, when assembled, the jacket is provided with pairs of these lugs 20 at the top and bottom edges of the jacket and at each corner thereof. Independent adjustment and expansion of the top and bottom portions of the jacket may thus be efiected. The sides and ends are held in proper alinement by the provision of interlocking fingers 2 1 and 25 projecting from the ends of the adjacent side and end walls or members in the planes thereof. As shown in Fig. 1, the side member 11 is provided with a pair of spaced apart fingers 2 1 while the end member 12 carries a single finger 25 adapted to engage between the fingers 24 and hold the ends and sides from vertical displacement relative to each other.

For the purpose of further strengthening the side members, each is provided, at opposite sides of the vertical web 15, with pairs of diagonally extending and intersecting ribs 26 formed integrally upon the exterior surface of the side 11 for reinforcing the latter, and these ribs may merge into longitudinal flanges or ribs 27 which extend along the exterior surface of the side adjacent the top and bottom edges thereof. F or facilitating the handling of the jacket, the end members 12 may each be provided with a handle 28 extending outwardly from the end members in position for ready grasping in the hand.v

It is apparent from this construction that the top and bottom portions of the molding jacket may be independently adjusted to take care of the exterior surfaces of molds where the sides thereof are inclined, or where the mold is of unequal dimensions at the top and bottom thereof. It will be further noted that the brace rod 16 is so located upon the side that internal pressure against the side is resisted by the brace rod, the latter having attachment at points near the ends of the side to evenly distribute the pressure on the brace rod between the upper and lower lugs 20.

What I claim is:

l. A molding jacket comprising side and end members having independent pairs of opposed lugs arranged at the upper and lower edges of the jacket and at the ends of said members, and means for independently connecting the upper and lower pairs of lugs to hold the ends and sides together.

2. A molding jacket comprising side and end members provided at their meeting ends with outturned lugs arranged in independent pairs at the top and bottom portions of the jacket, and means for independently and adjustably connecting the lugs of each pair.

3. A molding jacket having a side wall with an exterior vertical web intermediate its ends and exterior ears near its opposite ends, a brace rod adjustably secured at its ends to the ears and engaged over said vertical web.

4. A molding jacket having a side wall provided exteriorly with a vertical web intermediate its ends and ears at its opposite ends, and a brace rod adjustably connected at opposite ends to said ears and engaging intermediately over said web to reinforce the side against internal pressure, said side also having outstanding attaching lugs adjacent its upper and lower edges.

5. A molding jacket comprising side and end walls, and independent means for independently connecting the top and bottom portions of said side and end walls.

6. A molding jacket comprising side and end walls having at adjacent ends outstanding independent lugs located at the top and bottomportions of the jacket, and means for independently connecting together the adjacent outstandinglugs at the top and bottom portions of the jacket.

7. A molding jacket comprising side and end members, and means for separately connecting the upper andlower portions of the end members, said end members provided between the connected portions with adjustably interlocking means for holding the end and side members against edgewise displacement.

8. A molding jacket comprising side and end members, connections for the upper and lower portions of the side and end members at the corners of the jacket, and interlocking means arranged between the upper and lower port-ions of the jacket for maintaining the side and end members from edgewise displacement relative to each other.

In testimon whereof I affix m si nature in presence of two witnesses.
